MARSHAL T. REEVES, OF COLUMBUS, INDIANA, ASSIGNOR TO REEVES & 00., OF SAME PLACE.

CONNECTING-ROD FOR AUTOMATIC GATES.

SPECIFICATION forming part of Letters Patent No, 268,282, dated November 28, 1882.

Application filed September 25, 1882. (No model.)

To all whom it may concern:

Be it known that I, MARSHAL T. REEVES, a resident of Columbus, in the county of Bartholemew and State of Indiana, have invented a new and useful Improvement in Connecting- Rods for Automatic Gates, of which the following is a specification, having reference to the accompanying drawin My invention relates to that class of connecting-rods used in connection with a trip-crank to open and shut automatic gates, and particularly to that subdivision of such class in which the end of the connecting rod is slotted to receive the wrist-pin of the crank, and the 1 crank returns to its normal position automatically, alter having moved the rod and binge thereto connected.

The object of my invention is to prevent the jar occasioned by the sudden stoppage of the trip-crank when it recoils to its original or normal position.

My invention consists in a peculiar construction of the slot in the connecting-rod in which the wrist-pin moves, as hereinafter fully set forth.

The accompanying drawing illustrates my invention, in which a is. the trip-crank; b, the wrist-pin, and 0 part of the connecting-rod. The trip-crank is arranged to return automati- 0 cally to an upright position, as shown, after being depressed to open or shut thegate. I illustrate one method of so returning it by means of a spiral spring, d.

In this device as heretofore constructed the slot in the connecting-rod has been of about the same length as the short arm of the crank,

so that the wrist-pin rested against one end of the slot bel'orethe movement of the rod, and on its recoil struck against the other end 40 of the slot, ready to operate in the opposite direction, and not passing on its recoil beyond its normal position.

My improvement consists in making the slot longer than the stroke, so that the wrist-pin does not at any time reach the end of the slot, 5 but rests alternately in bearings eandf. Said hearings are adapted to hold the wrist-pin on one side, but to allow it to slip out when striking the other side, as clearly shown in the figure. That part of the slot between the bearings e and f projects below the general outline of that side of the slot for the purpose of guiding the wrist-pin beyond the bearing on the recoil of the trip.

The operation of my device is asfollows: The gate being closed, and the wrist pin ofthe crank resting in bearing 6, the trip is depressed in the direction indicated by the arrow, and the connecting-rod is carried forward in the same direction until the hinge is moved and the stroke is completed. The connectingrod is retained by the hinge, and the trip-crank recoiling the wrist-pin strikes against the in-' clined side of bearing 6, slips out of said hearing, passes along the depressed portion of the slot and beyond hearing f, passing h.e \ond its normal vertical position. On the return vibration it strikes the inclined side of bearingf, but does not reach 0. Alter a few vibrations the crank comes to rest in bearingf, and is ready to be operated in the opposite direction.

I claim as my invention- The cornbination,witharecoilingtrip-crank, ofa wrist-pin and a slotted connecting-rod, the bearings e f thereof having inclined sides joined by a depressed portion, substantially as shown and described, for the purpose set forth.
